Question

Medal to who ever helps
Part 1:
Solve the following system of equations. Please show your work to receive full credit.
x - y = 10
2x + y = 2

Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

I'LL CHOOSE THE ELIMINATION METHOD.
LEAST AMOUNT OF WORK. (11 STEPS)
x - y = 10
2x + y = 2 ADD
-------------
3X=12
X=12/3
X=4 ANS.
4-Y=10
-Y=10-4
-Y=6
Y=-6 ANS.
PROOF:
2*4+(-6)=2
8-6=2
2=2

Answer 4

Select the system of equations that corresponds to the given graph.

A coordinate plane shows two lines on the graph. One line crosses the y axis at (0, 2) and passes through the point (2,1). The other line crosses the y axis at (0,-2) and passes through the point (2,-1).

-2x - y = 4
2x + y = -2


-8x + 4y = -16
-4x + 2y = -8


x + 2y = 4
2x - 4y = 8


2x + 3y = 6
3x + 2y = 4
